It's the Feather you have been waiting for! The HUZZAH32 is the ESP32-based Feather, made with the official WROOM32 module. It has everything you love about Feathers: built in USB-to-Serial converter, automatic bootloader reset, Lithium Ion/Polymer charger, and just about all of the GPIOs brought out so you can use it with any of the FeatherWings.

That module nestled in at the end of this Feather contains a dual-core ESP32 chip, 4 MB of SPI Flash, tuned antenna, and all the passives you need to take advantage of this powerful new processor. The ESP32 has both WiFi and Bluetooth Classic/LE support. That means it's perfect for just about any wireless or Internet-connected project.

The ESP32 is a perfect upgrade from the ESP8266 that has been so popular. In comparison, the ESP32 has way more GPIO, plenty of analog inputs, two analog outputs, multiple extra peripherals (like a spare UART), two cores so you don't have to yield to the WiFi manager, much higher-speed processor, etc. etc! We think that as the ESP32 gets traction, we'll see more people move to this chip exclusively, as it is so full-featured.

Please note: The ESP32 is still targeted to developers. Not all of the peripherals are fully documented with example code, and there are some bugs still being found and fixed. All of the Featherwings work under the Arduino IDE, so you can expect things like I2C and SPI and analogue reads to work. But other elements are still under development. For that reason, we recommend this Feather for makers who have some experience with microcontroller programming, and not as a first dev board.

Here are specifications from Espressif about the ESP32:

  • 240 MHz dual core Tensilica LX6 microcontroller with 600 DMIPS
  • Integrated 520 KB SRAM
  • Integrated 802.11b/g/n HT40 Wi-Fi transceiver, baseband, stack and LWIP
  • Integrated dual mode Bluetooth (classic and BLE)
  • 4 MByte flash include in the WROOM32 module
  • On-board PCB antenna
  • Ultra-low noise analog amplifier
  • Hall sensor
  • 10x capacitive touch interface
  • 32 kHz crystal oscillator
  • 3 x UARTs (only two are configured by default in the Feather Arduino IDE support, one UART is used for bootloading/debug)
  • 3 x SPI (only one is configured by default in the Feather Arduino IDE support)
  • 2 x I2C (only one is configured by default in the Feather Arduino IDE support)
  • 12 x ADC input channels
  • 2 x I2S Audio
  • 2 x DAC
  • PWM/timer input/output available on every GPIO pin
  • OpenOCD debug interface with 32 kB TRAX buffer
  • SDIO master/slave 50 MHz
  • SD-card interface support

Huzzah32

Had a bit of trouble with the adafruit neopixel library. There are timing issues when using neopixels with the esp32 while the WiFi is enabled. Solved by using https://github.com/Makuna/NeoPixelBus instead. Really happy with the device.

AWESOME

Really can’t fault Cool Components, and the HUZZAH 32 is perfect for running Blynk sketches on for remote monitoring of sensors. Easy to use, and plenty of great tutorials out there.
